TK14551VTL Summary of contents

... Therefore, the TK14551V is suitable for high-speed data communication and can be used for various applications. The TK14551V is available in the very small TSSOP-24 surface mount package. ORDERING INFORMATION TK14551V January 2000 TOKO, Inc. APPLICATIONS Wide Band FSK Demodulation Wide Band FM Demodulation Video Signal Demodulation Wide Band ASK Demodulation ...

... ASK modulation, the IF input must be an unbalanced input. If the input is an unbalanced input as shown below, do not terminate Pin 1 (do not connect the bypass capacitor between Pin 1 and GND). If Pin 23 is the input do not terminate Pin 2. Page 18 APPLICATION NOTES do not terminate 1 1 January 2000 TOKO, Inc. ...

... The input resistance of the IF limiter amplifier is 1.5 k (see Figure 2). If the impedance of the filter is lower than 1 connect an external resistor between Pin 24 and Pin 2 or between Pin 23 and Pin 1 in parallel to provide the equivalent load impedance of the filter. Figure 2 shows an example of a filter with a 330 January 2000 TOKO, Inc OUTPUT ...

... This method does not have a feedback loop to control the gain because an AGC amplifier is not necessary (unlike the popularly used AM demodulation method). Therefore very useful application for some uses because it doesn’t have the response time problem. January 2000 TOKO, Inc 1.0 V. ...

... The Pin 4 input level should be saturated at the multiplier; if this level is lower easy to disperse the modulation output. Therefore, to have stable operation, Pin 4 should be higher than 100 mV The following figures show examples of the phase shifter resonance circuit January 2000 TOKO, Inc ...

... Pin 11 of the data comparator input established at a few tens of mV. But, as the demodulation level of the RSSI buffer amplifier output-2 is changed by the dispersion best to control variable resistor, etc possible to substitute the variable resistor for Vs. January 2000 TOKO, Inc BIAS ...
